## Half a Cup

 Category: Logic Submitted By: Scorefire Fun: (2.33) Difficulty: (0.98)

You are making a certain type of cake that requires half a cup of water. Unfortunately, you only have one that fills up to 1 cup, and another that fills up to 3 quarters of a cup. How can you measure half a cup?

Fill 1 cup of water, then pour it into the other cup so that a quarter of water remains in the larger cup. Then, empty the 3 quarter cup and pour the 1 quarter that is in the other cup into the 3 quarter cup. Fill 1 cup of water again, and pour the water into the 3 quarter cup until full, and you should have half a cup of water in the larger cup.

 Posted by Scorefire 12/10/10 Oops :lol: You can also pour three quarters of a cup into one and pour it into the other, then fill it up again, pour one quarter into the other to fill it and get half in the three quarter cup. My bad :lol: Posted by braingle100 12/10/10 Ya, fill the 3/4 cup, empty into 1 cup cup, that way the 1 cuppcup has 3/4 water. Next, fill the 3/4 cup and the pour into the 1 cupcup until full and 2/4 will remain in the 3/4 cup. Posted by lindee 12/18/10 Yay!I got it right. :D Posted by BaBeYdOlLlOvEr 12/24/10 I get it haha but hey i have a question what do you do to get POSITIVE KARMA? i dont know how to get it :( Posted by ojchahine 03/16/11 you could fill the first cup half way, ya know. Measuring cups have lines for a reason. Posted by Darkmagician92 04/09/11 easy one!! Posted by UofMWolv25 05/31/11 Alternatively, since you are making a cake, and you don't need to have 1/2 cup in a container...you can fill up the 1-cup...and then pour that in the 3/4-cup and pour the remaining 1/4 cup in the bowl...then do it again... 1/4 + 1/4 = 1/2 Posted by zembobo 11/17/11 I got the answer as it was posted but then read that there are easier ways! I like the comment above mine. Since it's a cake, you just need 1/4 twice which is easy. :)
